fix(templates/http-go): Remove scheduler flag from http-go build command

This removes the `-scheduler=none` flag from the build command in the
http-go template. Including this flag prevents Spin applications using
`http.Transport` from compiling.

```
❯ spin build
Building component http-roundtrip-test with `tinygo build -target=wasip1 -gc=leaking -scheduler=none -buildmode=c-shared -no-debug -o main.wasm .`
/opt/homebrew/Cellar/tinygo/0.35.0/src/net/http/transfer.go:213:2: attempted to start a goroutine without a scheduler
Error: Build command for component http-roundtrip-test failed with status Exited(1)
```
